A Guide to Ability Learning

Changing Dance-learning:
C2/5EE5: AD 0A 30 LDA $300A
C2/5EE8: 30 16 BMI $5F00
C2/5EEA: AE E2 11 LDX $11E2 (get combat background)
C2/5EED: BF 5B 8E ED LDA $ED8E5B,X (get corresponding dance #)
Notice how this one isn't labeled? Yeah, this took forever to find. Change the bolded byte to whomever you want.

Is there a way to set Dance Learning by Level Up ONLY?  I wanted to give this ability to Locke, but I didn't want him to learn them via the Battle Maps.
